BOEING MODEL 451 ( YK-15) Scout.

The somewhat unusual looking Boeing Model 451 was designed to meet a U.S.Army requirement for a liaison and observation type of aircraft,the criteria was for an aircraft that had a better than usual forward view and good low speed handling characteristics,the machine was intended to replace the many converted light aircraft used during WW2.
Started in 1946,two XL-15 prototypes were built from metal with fabric covered control surfaces,the huge flaps combines as a means of slow flight or collectively as wing spoilers that served as ailerons.The design of pod and boom had its advantages when dismantled and towed behind a vehicle or even transport by air to remote areas for use by the Army in its specialised role.
Despite the fact that a further ten aircraft were built,no further orders followed from the Army and the existing aircraft were handed over to the U.S.Forest service.
